Here is a screenshot of what I came up with, assuming a few things of course.Attachment 69729

your piston to deck height is probably out a bit. can you still see numbers on the front tab on the block? if thuse are still there it hasn't been decked, and your clearance would probably be around .025, if they are standard height pistons. looking at them they are likely a rebuilder style and the pin height is 1.540 vs. 1.56, making the clearance closer to .045. the heads are probably closer to 65-66cc, so your compression is going to be down from what you are thinking.
